"Mike Sims-Walker's return to Jacksonville lasted just two games and one catch.

Signed on Nov. 18 after being cut by the St. Louis Rams, Sims-Walker was placed on the injured reserve list Wednesday after the Jaguars claimed Brian Robiskie off waivers from Cleveland.

The Jaguars said Sims-Walker has a knee problem.

Sims-Walker wasn't at the two bye-week practices Tuesday and Wednesday, but said after practice Tuesday he couldn't talk because he had a tooth pulled."
