Waghorn is recovering from a knee injury at the moment, and Clark hopes that the 26-year-old striker returns to full fitness soon.
“It’s been unfortunate for Martyn, he’s done brilliantly for us and you don’t like to see anyone getting injured,” Clark told Rangers’ official website. “But he’s getting there and his treatment is going well. So hopefully he is back soon.”
Waghorn has been one of the best players for Rangers so far this season and is arguably the best striker in the Scottish Championship.
The former Sunderland and Leicester City man has scored 28 goals in all competitions for the Gers so far this campaign.
The injury to the Englishman is a blow for Rangers, but Mark Warburton’s side appear to be doing just fine without him.
The Gers are at the top of the Scottish Championship at the moment with 69 points from 27 matches.
The Glasgow giants are as many as 14 points clear of second-placed Hibernian, and it looks as though Rangers have sewn up the Scottish Championship title and automatic promotion to the Scottish Premiership at the end of the season.
