San Francisco 49ers defensive lineman Ronald Blair is on track to be available to play on Sunday against the Arizona Cardinals. Head coach Kyle Shanahan informed reporters on Friday that the team plans to activate Blair before the deadline to do so.

"Yes, he did get through the week," Shanahan said when asked if the team plans to activate the second-year player. "We plan to make that final whatever the deadline is. Most likely this afternoon or sometime early tomorrow."

In September, Ronald Blair was placed on injured reserve with a designation to return (short-term IR) due to a thumb injury he suffered during the preseason. He returned to practice with the team during the week of October 16, which made him first eligible this week to play in a game.

Failing to activate him before the Cardinals game would revert Blair back to injured reserve for the remainder of the season.

Blair, 24, was a fifth-round draft pick out of Appalachian State by the 49ers in 2016. He appeared in all 16 games for the team last season while recording 11 tackles and three sacks.
