Meinrod is projected to undergo surgery sometime in the next three weeks.
"I'm happy with the way I played against Miami and I'm excited about starting," Niblock said.
It appears the injury to Cromartie's right hip is less severe than originally anticipated. He attended practice on Monday, but his participation was limited to stretching. Bowden said they plan to examine Cromartie's injury on a day-to-day basis to determine whether he'll be ready for Saturday's game.
"It feels a little bit better. The first time I hurt it didn't hurt as bad as it did in the game. We're gonna take an MRI on it and find out later this week what's going on," Cromartie said.
Cromartie initially injured his right hip during preseason workouts . He re-aggravated the injury this past Friday when he fell defending a play against Miami, landing with all his weight on the hip.
Before leaving the game against Miami, Cromartie returned a fumble for a touchdown, the first of his career and intercepted a pass from Miami QB Brock Berlin.
The plan for offensive linemen Castillo and Meeks is to give them an increasing number of reps over the next week in hopes of having them ready in time for Saturday's game.
"I'm anxious to see tomorrow, when (Meeks) is in pads, how much pressure he can put on that ankle," Bowden said.
