Howard Balzer of the St. Louis Globe-Democrat reports that the St. Louis Rams will sit out the 2010 Supplemental Draft.

The Rams were believed to have some interest in BYU running back Harvey Unga, who expressed interest in playing in the same backfield as Steven Jackson, but Balzer points out several reasons why the Rams would give pause before submitting a bid this morning.

Tampa Bay, Seattle, and Miami were the other teams that have reportedly expressed the most interest in the 6-1, 244-pound Unga.

The 2010 Supplemental Draft begins at 1pm ET, and is conducted via e-mail.
