Browns quarterback Jake Delhomme missed his second straight practice because of an injured right ankle.
Cleveland coach Eric Mangini said Delhomme has made progress with his ankle, which he hurt while throwing an interception in the closing minutes of the first half in Sunday's season-opening loss at Tampa Bay. Delhomme has been wearing a walking boot to stabilize his ankle.
If Delhomme is sidelined for Sunday's home opener against Kansas City, backup Seneca Wallace will make his 15th career start. Wallace, a career No. 2 QB, took all the snaps with Cleveland's first-team offense on Wednesday. He's expected to do so again Thursday.
Not wanting to tip their hand, the Browns could wait until game time Sunday against the Chiefs before making a decision on Delhomme, who threw two interceptions in his debut for Cleveland. Mangini said Delhomme could start, be the backup or Cleveland's No. 3 emergency quarterback.
"I think Jake's made some progress," Mangini said. "We have a couple different approaches how the game can go and we'll just have to see which way it goes."
Delhomme said Wednesday that he has missed an entire week of practice with Carolina because of a thumb injury, but still started.
Nose tackle Shaun Rogers and rookie offensive guard Shawn Lauvao also missed practice for the second day in a row.
