Lancashire captain Glen Chapple has been given the coaching role for the first XI for the remainder of the season, the club confirmed on Friday afternoon.
"It is crucial that we minimise the disruption to the cricket department while we are in the middle of an important run of matches and therefore we need to ensure that we have continuity and provide support, leadership and resources to help us achieve our aims and objectives," Watkinson said in a statement.
"In his position as club captain, Glen Chapple will have responsibility for the first team squad. Gary Yates will support Glen and spend the vast majority of his time around the first team squad."
Chapple has played for Lancs since 1992.
