Ospreys, leading 14-5, had been hunting a try to stretch their lead when the ball went loose and Sharks broke away.
Jones, a former wing with Scarlets and Wales, stressed his player was just trying all he could to prevent a key score.
“Luke Morgan is a competitive guy. He’s chasing back as hard as he can for his team in what was a tight game,” Jones said.
“He’s done his absolute utmost to do what we ask players to do, which is not give up until the ball is grounded.”
Jones said Morgan was “well within his right to try to dislodge the ball” as Hooker went over.
“Ethan Hooker is a great player and unfortunately he got injured in that incident, but there’s no malice in that challenge,” he added.
“It’s really unfortunate that Ethan got injured – he’s a top-quality player and we hope he won’t be out of the game for too long – but Luke was just trying his best to do what he could for his team.”
There were reports that Sharks had asked for the incident to be investigated by the URC, but Ospreys have had no complaints from the citing commissioner and Morgan is available to face Cardiff on Friday night.
“He’s a pretty resilient guy,” continued Jones. “He’s played professional rugby at the highest level.
“But I can imagine that as resilient as you are, you don’t want to be having to deal with that on behalf of your family, you just want to get on with the sport you love.”
