The game on Wednesday evening will be Rangers’ fourth in 14 days, with the match against Dumbarton at the weekend taking the total to five in two weeks, and the manager is likely to make changes to his side in a bid to keep them fresh.
The Gers are at a crucial point in the season as they continue to challenge Hibernian for second place and the tired state of his players could become an increasing issue going into the end of the season.
The pressure is on Rangers to come away from Livingston with a win and pull three points clear from Hibs, leaving the Edinburgh side playing catch up after their Scottish Cup semi-final at the weekend.
Speaking to the club's official website, McCall outlined his plans to make changes to his team amid the congested fixture list.
“We played with 10 men against Hearts for a large part of the game and then we were down at Queen of the South on Thursday and then had a game on Sunday,” he said.
“We have had a lot of games in a short space of time so we will need to freshen up ahead of Livingston.
“The lads will be in on Monday but it is more a case of them getting mollycoddled, massaged and in the pool to recover.
“We need to be fresh and have that energy about us for Wednesday because we are certainly up against a team who have a lot to play for.”
Livingston are currently rock-bottom of the Scottish Championship and are in desperate need of a win to take them level on points with Alloa, and as McCall has pointed out, will provide the Light Blues with a very difficult test given they have so much riding on the match.
The Rangers manager has called upon the youngsters to help bolster the team this season, with Robbie Crawford Man of the Match from the Raith Rovers game and Andy Murdoch playing the entire 90 minutes as all of Rangers' young recruits continue to impress.
McCall does have options on the bench but may be reluctant to replace some of his in-form players after they made such a strong recovery from the defeat against Queen of the South.
