Lions sign four 2013 draft picks

The Detroit Lions' rookie minicamp begins on Friday, and the expectation is for nearly all of their 2013 draft picks to be under contract before it comes to a close on Sunday. Contract negotiations are pretty straightforward nowadays, especially for non-first-round picks, as evidenced by the fact that the Lions signed four of their 2013 picks on Wednesday afternoon.

According to Aaron Wilson, the Lions have signed sixth-round picks Corey Fuller and Theo Riddick and seventh-round picks Michael Williams and Brandon Hepburn. These players were the Lions' final four picks of the 2013 NFL Draft, and all of them received four-year deals.

Via Wilson, here are more details on each player's contract:

• WR Corey Fuller - 4 years, $2.283 million ($123,100 signing bonus)
• RB Theo Riddick - 4 years, $2.25 million ($91,000 signing bonus)
• TE Michael Williams - 4 years, $2.22 million ($65,148 signing bonus)
• LB Brandon Hepburn - 4 years, $2.205 million ($45,896 signing bonus)

With these deals complete, Ezekiel Ansah, Darius Slay, Larry Warford, Devin Taylor and Sam Martin are the only Lions draft picks that still need to sign.
