Morris injured his back on the tour of England and is expected to
return to action with the Titans in the middle of the T20 Challenge with the tournament scheduled to get underway on Friday.
The 30-year-old says he will still have the same pace but will have a
much smoother action, which is where Gibson - who is England's former
bowling coach - has helped.
In an article published on ESPNCricinfo, Morris said: "I've had a few
tweaks in my action that Ottis has changed. I had to iron it out
because it wasn't good enough - simple as that.
"I think in striving for a bit of extra pace, there was some twisting
in my action.
"I was getting lazy and doing quite a lot of twisting, which caused a
lot of pressure on my lower back and inevitably caused the injury."
Morris is one of a number of Proteas pace bowlers that is currently
on their way back from injury and Gibson has said that Dale Steyn will
return straight to the Test side if he recovers from injury.
Along with Morris and Steyn, Vernon Philander and Morne Morkel will
also have their fitness monitored over the next few weeks.
Morris admits that he is
still hungry and motivated to do well for the Proteas.
"It's always good to know that the coach is backing
the guys who aren't playing, especially with injuries because that's
part of the game.," he said.
"If a youngster is better than me he must play, it's as simple as
that, but I'm always going to be fighting for my spot because playing
for South Africa is what I want to do. If I never play for South Africa
again it's cool, but I'm going to give it my best shot."
