SANTA CLARA -- The 49ers are open to defensive lineman Justin Smith keeping alive the possibility of an in-season return to the playing field, sources told CSNBayArea.com.
Defensive lineman Justin Smith might be leaning toward retirement, but he said he has not fully made up his mind.
The 49ers are likely to lose two of their top defensive players to retirement, according to sources.
Free agent defensive lineman Darnell Dockett, whom the Arizona Cardinals released last week, is visiting with the 49ers on Tuesday, a league source told CSNBayArea.com.
The 49ers have yet to make any cost-cutting moves this offseason. A year ago, they released veteran cornerback Carlos Rogers to gain cap relief.
