Wake-up call: Combine, Day 4

INDIANAPOLIS -- Setting the schedule for the fourth day of the NFL Combine (full four-day agenda here):

Focusing on the back end. This is the day that cornerbacks and safeties are scheduled to come to the media center for interviews. It is also possible that some of the defensive linemen and linebackers who didn't make it over on Saturday could come by, such as Boston College linebacker Luke Kuechly.

Wrapping up the pro side. A total of 44 NFL head coaches and personnel executives held news conferences at the combine over the last three days. Sunday is almost always quieter on that front. The lone news conferences today are media-based, with NFL Network analysts Mike Lombardi and Mike Mayock later in the day.

Who's working out? Quarterbacks, receivers and running backs. For the Patriots, who figure to be looking closely at receivers, how well some of the bigger targets run will be important information today.
