If Major Wright's or Chris Williams' hamstring injuries result in the Bears looking for help at tackle and safety they could be out of luck, according to an NFL source.
According to the source, the current free-agent market is extremely thin at tackle, safety and linebacker in large part because players with NFL experience have been swallowed up by UFL teams and are therefore unavailable.
The UFL regular season ends on Nov. 20, at which time players from that league will be available to sign with NFL teams, which could provoke a signing frenzy, especially for teams that have been trying to replace injured players.
Free-agents typically work out for interested teams on Tuesdays.
The lack of experienced players on the market could also increase the value of what few proven players are available, such as Chargers holdout left tackle Marcus McNeill and receiver Vincent Jackson.
