Dowell (knee) was designated to return from the reserve/PUP list Monday, Jim Wyatt of the Titans' official site reports.
Dowell now has a 21-day window to practice with the team, a timeframe that carries through to the end of the regular season. However, Dowell could be activated beforehand and still see game action before the conclusion of the campaign. The UT Martin product suffered a torn ACL in December of last year and has been out of action since, so it may take him some time to get back up to speed.
