Michael Sam's Twitter account is still @MichaelSamNFL. He hasn't been employed by the NFL since late October.

But Sam hasn't given up. He has been accepted to participate in the first NFL veteran combine on March 22 in Arizona. That news was first reported by ESPN's Adam Schefter....

Sam, of course, is still vying to be the first openly gay player to appear in an NFL regular-season game. The defensive end out of Missouri was drafted in the seventh round by the St. Louis Rams last year. He was cut at the end of a fairly productive preseason, and the Rams didn't sign him to their practice squad. The Dallas Cowboys signed him to their practice squad but cut him on Oct. 21.

Sam has signed up to be on "Dancing with the Stars," but the NFL door isn't closed for him. It's not going to be easy for him though. Any team could have signed him since the Cowboys cut him, but that hasn't happened. Maybe a good workout will help him. An underwhelming performance at the college combine a year ago probably negatively affected his draft stock. He is viewed as not big enough to be an NFL defensive end and not explosive athletically enough to overcome that or transition to outside linebacker. Maybe he could change what the NFL thinks of him with a great veteran combine.
