Ulster hooker Rob Herring has been cleared of a stamping offence and will be eligible to play in Friday's Pro12 semi-final against Glasgow.
Herring, 25, was cited for allegedly stamping on an opponent in Saturday's defeat by Glasgow but the charge was not upheld at a hearing on Wednesday.
The panel ruled that Herring had been held by two opponents in a ruck and was attempting to release himself.
Ireland star Rory Best is likely to return at hooker for Ulster on Friday.
The disciplinary hearing in Cardiff was chaired by Roger Morris, who sat along with other Welsh officials Nicholas D Jones and Ray Wilton.
South African-born Herring played the full 80 minutes of last weekend's match at Scotstoun as Glasgow clinched a 32-10 victory.
Glasgow finished top of the Pro12 standings, earning home advantage for Friday's play-off tie at the same venue.
