RICHMOND defender Steven Morris has revealed the extent of his injuries after Adelaide key forward Taylor Walker spear-tackled him during the last quarter of the Crows' victory at AAMI Stadium at the weekend.

Speaking at the announcement of his contract extension, Morris said he suffered neck stiffness and pain down the right hand side of his body after the tackle that dumped him on his shoulder.

"Taylor came up to me after the game and asked if I was OK and I appreciate that and life goes on," Morris said.
 
Morris had scans on Monday that cleared him of structural damage.

He hopes to train on Thursday to be given the all-clear for Richmond's match against Melbourne at the MCG on Saturday.

Morris went into the game against Adelaide coming off a shoulder injury that had forced him out of the Tigers' previous match, against Greater Western Sydney in round 12.

"I got through the game and hopefully the worst of that's gone by," Morris said.

Richmond's medical report on Morris prompted the Match Review Panel to rate Walker's conduct as reckless with medium impact.

Walker was offered a three-match sanction, which he accepted.

Walker was also suspended for two matches after round seven for a sling tackle on Geelong defender Harry Taylor. The 22-year-old was reprimanded after round five for making front-on contact to Port Adelaide defender Jacob Surjan.

"I was surprised I didn’t get the free kick at the time, but we all make mistakes and I'm looking forward to next week now," Morris said of the Walker spear-tackle.

Walker was paid a free kick for holding the ball.

Morris, 23, who was recruited from West Adelaide before this season, said he was excited by the extension of his contract by 12 months, taking him through to the end of 2014.

He said he's worked mainly on improving his composure since making his debut against Carlton in round one.

"Hopefully I can continue to improve," he said.

Morris - the son of dual Richmond premiership player Kevin Morris - is averaging 15 disposals per game this year.

Morris was speaking after a coaching clinic for schoolchildren at the Sir Henry Olney Oval in Yarra Bend.
