If anything brings the NFL and the locked out Referees Association back to the bargaining table, it might be this weekend's replacement clinic in Dallas. Referred to as the "scab clinic" by NFLRA officials, it's a collection of referees who've been working lower-level football, some retired officials and others who aren't currently working at the Division I level. If the replacements are in play, a bit of NFL history will be made. According to Sam Farmer of the Los Angeles Times, one of the replacements is Shannon Eastin. She's worked Mid-Eastern Athletic Conference games, but would be the first woman to work an NFL game as an on-field official.
