Coach Sean McVay said that Forbath (ankle) will go on injured reserve, Kevin Modesti of the Los Angeles Daily News reports.
Los Angeles has a kicker turnstile on its hands, with Forbath now out of commission after taking over for rookie Samuel Sloman. Forbath went 2-for-3 on field-goal tries and 4-for-5 on extra points during his two active games for the Rams, but with him now unavailable, Matt Gay and Austin MacGinnis are being considered as practice-squad pickups. The Rams have an upcoming Monday night game against the Buccaneers for Week 11, a contest during which margins may be slim and placekicking therefore particularly important.
