The Browns began their practice week Wednesday in preparation for the Cincinnati Bengals without two key defenders: rookie defensive end Myles Garrett and strongside linebacker Jamie Collins.

But coach Hue Jackson provided a reason to believe Garrett could return in time to play Sunday when the Browns (0-3) host the Bengals (0-3).

"He's close," Jackson said. "I think there's a chance he'll practice this week before the week's out, so we'll see where we are after that."

Jackson was asked if Garrett needs more than two or three days of practice to make a comeback.

"No, he just needs to practice," Jackson said. "If he is able to play, we might not play him the whole game. So we'll see how that unfolds if he's able to go. We'll find out more as we go through the week."

Garrett missed the first three games this season with a right high-ankle sprain he suffered Sept. 6, and Collins sat out Sunday against the Indianapolis Colts with a concussion he suffered Sept. 17 against the Baltimore Ravens. Jackson said Collins remains in the NFL's concussion protocol.

Garrett spent the half-hour portion of Wednesday's practice open to reporters on a stationary bike. He has been running and doing agility drills since last week.

Collins wasn't on the field during the open portion.

Wide receivers Kenny Britt (knee) and Sammie Coates (hamstring) and tight end Randall Telfer (knee) were on the stationary bikes, too. Jackson said Britt will return to practice this week.

Left tackle Joe Thomas (knee) didn't practice, either. He wasn't the field, but he usually takes Wednesdays off.
