Former Rangers and Scotland boss Walter Smith is recovering in hospital after undergoing an operation.
The 73-year-old watched his former club be crowned champions for the first time in a decade last weekend and spoke of his pride at Steven Gerrard ending their wait for a Premiership title.
The Ibrox icon has been a regular follower of the club and has appeared as a guest on club TV earlier in the season.
He went under the knife earlier this week for an unknown procedure but is now said to be making progress in his recovery.
A Rangers statement read: "Rangers Football Club can confirm Walter Smith had an operation on Monday and he is currently recovering in hospital. His family have requested privacy at this time."
Smith - dubbed as an "unofficial mentor" by Gerrard - won 13 trophies in his first spell at the club between 1991 and 1998 after he stepped up from assistant manager to replace Souness.
He returned in 2007 after walking away from the job as manager of the national side, leading the Ibrox club to three consecutive titles and the UEFA Cup Final in Manchester in 2008.
He retired at the end of the 2011 season but returned to his boyhood club as non-executive chairman in 2013.
