Rookie inside linebacker Reuben Foster was moving around the locker room without his walking boot or a noticeable limp Tuesday, nine days after he sustained a high ankle sprain in the season opener.
That’s an encouraging sign for the 49ers, who have been replacing Foster with Ray-Ray Armstrong and, briefly, Brock Coyle.
Foster won’t be available for Thursday’s game against the Rams, and defensive coordinator Robert Saleh indicated Coyle could play more in his absence. In a 12-9 loss at Seattle on Sunday, Coyle replaced for Armstrong for a six-snap series in the second quarter.
“He deserves it,” Saleh said when asked why Coyle entered the game.
