The Patriots brought in free-agent receiver Gerrard Sheppard for a workout Wednesday, a source told the Houston Chronicle’s Aaron Wilson. Sheppard previously played for the Baltimore Ravens and Green Bay Packers. He went undrafted out of Towson in 2013.

Why? I guess for TC and pre-season purposes only I hope.
