Players, coaches and supporters were left bemused after Exeter Chiefs wing Olly Woodburn was sent off after attempting to prevent Leicester Tigers winger Chris Ashton from scoring a try.
With the Tigers leading 22-12 at the time, No. 8 Jasper Wiese broke clear which eventually resulted in former England wing Ashton sliding over at the far right-hand corner. As Ashton crossed, he was tackled by Stuart Hogg before Woodburn dived in to help the Scotland full-back prevent another Leicester try.
Initially it looked as if the score was going to be disallowed, with the replays showing Ashton's foot had brushed the touchline, but referee Karl Dickson decided Woodburn had dived on Ashton and prevented him from scoring, with a penalty try awarded as a result.
