Everyone wants to know ... did Michael Irvin and Steve Smith throw fists after their heated smack talk session on "NFL Network" last night???
Michael tells TMZ Sports ... when the cameras shut off, it was definitely more love than war -- but their dispute ain't over yet.
The whole thing started during the TNF pre-game show -- Smith was offended when Michael said the Ravens haven't had a solid go-to WR since Anquan Boldin.
Smith shot back saying his stats (and his route running!!) dominated Irvin's -- and at one point, it seemed like the two might come to blows!
