ALLEN PARK — Cornerback Chris Houston said he will practice on Wednesday. This is good news for the Lions secondary as they prepare to play the San Francisco 49ers on Sunday night.

Houston has not practiced since he sustained a high ankle sprain on Aug. 25 in the third preseason game.

Jacob Lacey started for him in Sunday’s win over the St. Louis Rams.

The patched-up secondary played a solid game but got tons of help from the defensive line and the secondary.

Free safety Louis Delmas has not practiced since Aug. 7 knee surgery. He did not speak to reporters today and coach Jim Schwartz would not offer information on his status. John Wendling got the start for Delmas.

Rookie cornerback Bill Bentley suffered a concussion in the third quarter on Sunday. Schwartz said he will have to go through a certain protocol to be cleared for contact.

Schwartz, who was in good humor following Sunday’s win, said he has seen 49ers coach Jim Harbaugh several times since their famous “handshake” following the 49ers win at Ford Field last season.

Since then Schwartz said they have shaken hands several times “without incident.”
