Deion Sanders tweeted Saturday that he is "ashamed" of 31 NFL teams after Isaiah Bolden was the lone HBCU player drafted this year.

Bolden, a cornerback and returner for Jackson State, was selected by the New England Patriots in the seventh round.

Sanders, now the coach at Colorado, coached Bolden at Jackson State.

"So proud is you @isaiahbolden23 You deserved to be drafted much higher but I'm truly proud of u," Sanders wrote on Twitter. "I know how much u want this. I'm ashamed of the 31 other @nfl teams that couldn't find draft value in ALL of the talented HBCU players & we had 3 more draft worthy players at JSU."

Four HBCU players were selected in last year's NFL draft.
