The 49ers are 1-6 and have lost five-straight.

They now travel to Arizona to face the Cardinals for the second time in four weeks after a 28-18 loss at Levi’s Stadium. The 49ers committed five turnovers in that game and gave the Cardinals their first and only win on the season. It’s safe to say that this feels like a must-win for Kyle Shanahan’s squad.Here are five players to watch when the 49ers battle the Cardinals on Sunday:WR Dante PettisPettis makes his anticipated return against the Cardinals after missing nearly four games due to a knee injury suffered during a punt return in the opening minutes of the 49ers’ Week 4 contest against the Los Angeles Chargers. In three games http://www.authenticssanfrancisco49ers.com/cheap-pierre-garcon-jersey , the 49ers’ rookie reeled in three receptions for 96 yards and a touchdown while averaging 32-yards per reception. Pettis seemed like a big play waiting to happen during limited action.Veteran receiver Pierre Gar莽on (shoulder/knee) was ruled out Saturday, increasing the likelihood we see plenty of Pettis against the Cardinals. The 49ers’ receivers have underwhelmed so far this season. Perhaps a healthy Pettis will add a new dynamic for struggling quarterback C.J. Beathard. LB Reuben FosterAll eyes with be on the 49ers’ second-year linebacker when he takes the field Sunday. Foster was the topic of discussion this week after fighting through a shoulder injury that’s plagued him for weeks. Both Shanahan and coordinator Robert Saleh acknowledged the injury that Foster said won’t require surgery after undergoing an MRI.Foster’s struggled so far this season, grading out as one of Pro Football Focus’ worst linebackers through seven games. It’s unclear if the shoulder is the sole cause for the massive drop in production, but it’s impact is evident on the field. We took a more in-depth look at Foster’s struggles here. Keep an eye on the 49ers’ second-round pick Sunday as he looks to regain his 2017 form.DL Solomon Thomas28 picks before the 49ers selected Foster at No. 31, they drafted Stanford defensive lineman Solomon Thomas third-overall. So far, Thomas has underwhelmed in his limited role on the 49ers’ defensive front. Thomas’ success at Stanford was along the interior of the defensive line, but he's been relegated mostly to defensive end with the 49ers - until recently.Thomas played more snaps along the interior of the 49ers’ defensive line against the Rams in Week 7 than he has in any other game this season. The results were a step in the right direction White Richard Sherman Jersey , receiving the third-highest game grade (77) of his career, per PFF. Thomas’ usage and alignment will be worth watching against the Cardinals.QB C.J. BeathardBeathard boosted his stock after an impressive Week 6 performance opposite Aaron Rodgers in the 49ers’ 32-30 loss to the Green Bay Packers on Monday Night Football. Unfortunately, Beathard followed that up with an abysmal afternoon against the Rams at Levi’s Stadium, completing 15 of 27 for 170 yards, one touchdown, two interceptions and two fumbles. The 49ers’ 39-10 Week 7 loss to their NFC West opponent is currently the low point of the season.Beathard’s worst game of the season prior to the Rams was against the Cardinals, also at Levi’s Stadium. He’ll have a chance to redeem himself as the 49ers head to Arizona for a rematch just three weeks later. Shanahan is already fielding questions as to when we may see the debut of backup quarterback Nick Mullens. Beathard must put together a respectable showing if he wants to maintain his leading role Youth Mike Person Jersey , and more importantly, give the 49ers a chance at their second win.CB Richard ShermanSherman missed the 49ers’ Week 7 contest against the Rams with a calf injury. He’s remained questionable to play against the Cardinals all week, but he is expected to return to action on Sunday. Sherman’s calf injury has cost him three games so far this season.Despite some missed time, Sherman has been everything the 49ers’ hoped for so far in 2018, essentially shutting down an entire side of the field for San Francisco’s secondary. His veteran presence is a welcome addition to a secondary that’s struggled with missed assignments. Sherman’s already said that if he plays Sunday, he’s unsure if he’d be able to go against the Raiders the following Thursday. His ability to maneuver on Sunday will be worth watching.Maybe it’s finally Antone Exum’s time It’s a familiar story: a player is highly touted out of college and in high demand, looking to make the next step Youth Dante Pettis Jersey , until a devastating injury changes the course of their path. After his junior year at Virginia Tech, Antone Exum Jr.was a player who was projected to go in the first or second round after he had a stand out season his junior year. Exum played safety in his first two seasons in college and played well but it was the he switched over to play cornerback and recorded five interceptions that people really started to take notice. Then everything changed. In the spring of 2013 he tore his ACL and lateral meniscus in a pick up basketball game. In 2014 he sat out the first seven weeks as he continued to rehab from surgery. In his third game back he sprained his ankle and his season, again, was over. Exum was drafted in the 6th round, 182 overall pick, in the 2014 draft by the Vikings. He played in 26 games for Minnesota before going on IR in December of 2015 from injuries to his shoulder and ribs. In 2016 he suffered a knee injury in game preseason game and the Vikings placed him on IR for the remainder of the season. In May of 2017 during Vikings OTAs a teammate fell into Exum’s leg and he again suffered a knee injury. He was cut by the team in September and remained a free agent until the 49ers signed him in November. In June the team signed Exum to a one year contract in June, 2018 and then subsequently cut him on September first and signed him again on September third as the team set it’s 53 man roster. With the health of the 49ers secondary in question http://www.authenticssanfrancisco49ers.com/cheap-laken-tomlinson-jersey , namely Jaquiski Tartt (shoulder) and Adrian Colbert (hip), Exum has found himself in a starting role on the defense. Exum started off the game with a bang, surprising Philip Rivers and the crowd at Stub Hub Center in the first drive of the game coming up with a pick six on a pass intended for Keenan Allen. He continued to impress, ending the day with three solo tackles and three pass breakups in addition to his interception. He remained humble after the loss and spoke about the defense’s preparation throughout the week:The defense is still having difficulty missing tackles in games but at least they did seem to improve in the first half of the game. While Colbert was healthy enough to dress in Los Angeles, he only went into the game on special teams as he is not completely healthy and did not get enough practice reps throughout the week according to Kyle Shanahan. Tartt is expected to return to practice this week in a limited capacity but until the two are healthy, Exum will have his chance to show he is capable enough to hold down a spot on the roster.
