Defensive tackle Sen'Derrick Marks and defensive end Scott Solomon both missed practice for the second straight day for the Tennessee Titans with knee injuries.
However, Coach Mike Munchak is still hopeful that they could practice Friday and perhaps play in Sunday's season opener against the New England Patriots.
Marks is making his way back from a sprained MCL in his right knee, while Solomon had arthroscopic knee surgery on his right knee last week.
Coach Mike Munchak ruled tackle Mike Otto out for Sunday, as he recovers from both surgery on his right hand and having his right knee scoped as well.
Guard Steve Hutchinson did not practice on Thursday, but was simply getting a day off to rest.
Defensive tackle Jurrell Casey (elbow) and linebacker Zac Diles (hamstring) both practiced fully for the second straight day.
