An attempt to reach Walker via telephone Sunday night for a comment on his visit to South Bend and the status of his commitment to Louisville was unsuccessful.
"He really doesn't want to talk with anyone about his recruitment until about Wednesday," Walker's mother told InsideTheVille.com "He just got back from his visit (to Notre Dame) and he wants to let all this information soak in before he makes his decision."
The 6-2, 190-pound Walker, rated the #6 punter nationally, is expected to announce his decision this week.
"I plan to make a decision by next Wednesday or so," Walker told IrishEyes.com last week.
Three Louisville coaches, including head coach Steve Kragthorpe, visited Walker last week.
