DE Buchanan signs contract

The New England Patriots on Tuesday signed defensive end Michael Buchanan, who was selected by the team in the seventh round of last month's draft.

Buchanon's signing leaves the Patriots with just one unsigned selection, wide receiver Aaron Dobson (second round).

Earlier this month, ESPNBoston.com's Field Yates provided the following scouting report of Buchanan, who led Illinois in sacks last season.
