49ers vs. Panthers injury report: San Francisco rules two out for MNF

The San Francisco 49ers are preparing for their Week 12 Monday night showdown with the Carolina Panthers at Levi's Stadium, and with that, they held their final practice of the week on Saturday.

Addressing reporters after the session, 49ers head coach Kyle Shanahan revealed that the team will be without kicker Eddy Piñeiro (hamstring) and linebacker Tatum Bethune (ankle) on Monday.

Pineiro has been great for San Francisco this year, making all 22 of his field goal attempts. The 49ers will likely elevate Matt Gay from their practice squad to take his place for this battle.

Bethune stepped up into a starting role when Fred Warner suffered his season-ending injury and has been solid thus far. Without him, Curtis Robinson will take the snaps alongside Dee Winters on Monday.

The 49ers are also listing defensive end Robert Beal Jr. (concussion) as doubtful and linebacker Luke Gifford (hip/neck) as questionable.

Beal suffered a concussion in the team's Week 11 win over the Arizona Cardinals. He hasn't practiced all week, so even if he's cleared on Sunday, it wouldn't be surprising to see him sit out the game. San Francisco will have to rely on Bryce Huff, Sam Okuayinonu, Clelin Ferrell and Keion White as their edge rushers.

Gifford has mostly played on special teams this year, but has been on the field for 140 defensive snaps (19%) as depth. If he can't go, the 49ers would have just Winters, Robinson and third-round pick Nick Martin at the position on the roster. They also have Jalen Graham and Stone Blanton on the practice squad, who they could call up if needed.
