Carolina Panthers running back Chuba Hubbard is being placed on injured reserve due to calf and knee injuries, multiple media outlets reported Saturday.

Hubbard initially was listed as questionable for Carolina (4-11) in its game on Sunday against the host Tampa Bay Buccaneers (8-7).

Raheem Blackshear is the lone running back remaining on the Panthers’ active roster. He has three carries for 13 yards this season.

Signed to a four-year, $33.2 million contract extension last month, Hubbard has recorded career-high totals in rushing yards (1,195), rushing touchdowns (10) and catches (43) in 15 games (all starts) this season.

Hubbard, 25, is coming off a 152-yard, two-touchdown performance in the Panthers’ 36-30 overtime victory over the Arizona Cardinals on Sunday. The Alberta native capped the day with a 21-yard touchdown run in overtime. He earned NFC Offensive Player of the Week.

Hubbard has rushed for 3,175 yards with 22 touchdowns to go along with 121 catches for 749 yards and two scores in 64 career games (39 starts) with Carolina. He was selected by the Panthers in the fourth round of the 2021 NFL Draft out of Oklahoma State.
