Carolina Panthers coach Matt Rhule announced Monday that star running back Christian McCaffrey remains week-to-week with a shoulder injury.

ESPN, however, reported that it’s unlikely that McCaffrey would play for the Panthers (4-7) on Sunday (1 p.m. ET) against the host Minnesota Vikings (4-6).

McCaffrey suffered an AC joint injury in his right shoulder in Carolina’s 33-31 loss at Kansas City on Nov. 8, his first game action since Week 2. He sat out the Panthers’ 46-23 loss to Tampa Bay on Nov. 15 and a 20-0 victory over Detroit on Sunday.

Signed to a four-year, $64 million contract extension in the offseason, McCaffrey has rushed for 225 yards and five touchdowns and caught 17 passes for 149 yards and one score in three game in 2020. He suffered a high ankle sprain in Week 2.

In 2019, McCaffrey gained an NFL-high 2,392 yards from scrimmage and scored 19 touchdowns from scrimmage, which tied for the league lead.

Mike Davis once again is expected to serve as the primary running back for the Panthers on Sunday.
