Mat Luamanu joined Harlequins from Benetton Treviso last summer

Harlequins back row Mat Luamanu has been banned for three weeks by the Rugby Football Union for "dangerously charging" Sale forward Josh Beaumont.

Luamanu, 27, was sent off for the no-arms tackle in the closing stages of the Sharks' 19-10 victory on Friday.

The 6ft 3in, 20st 7lb forward will miss the Premiership fixtures against Exeter, Saracens and Wasps, and will be available again on 3 October.

Sale back rower Beaumont had to leave the pitch after the 71st-minute tackle.
