Kilmarnock chairman Michael Johnston has revealed manager Kenny Shiels will have his position reviewed.
The decision comes after Shiels was handed a four-match ban for his latest outspoken media comments.
Shiels, who previously landed in hot water when he accused a match official of lying, then described Celtic as "the monster of Scottish football" following a row with Hoops boss Neil Lennon.
But Johnston claims the Killie board have been concerned by the team's failure to reach performance targets.
Kilmarnock were in the driving seat for a top-six finish but could only manage one point from two home matches against St Mirren and Dundee in the final pre-split fixtures.
Killie then slumped to four defeats in the five post-split games.
"Kenny's position is under review at present," Johnston told the BBC.
"This is due to his failure to meet a contractual performance-related target and potential breaches of contract relating to media comments and observance of Scottish FA articles and rules and SPL articles and rules."
