The Detroit Lions have re-signed cornerback Paul Pratt and released defensive tackle Robert Callaway, John Niyo of the Detroit News reports.

Pratt went undrafted coming out of Nevada in 2009, but joined the Lions' practice squad in November after leading the UFL in interceptions.

The Lions released Pratt after signing Dre Bly on July 2.

Callaway, a 6-5, 312-pound undrafted free agent from Saginaw Valley State had been with the club since April.
