WWE star Bill Goldberg just showed up to Junior Seau's memorial in Oceanside, CA ... showing signs of encouragement.
On his way in, Bill told us, "Nobody will ever understand the positive difference that Junior made to this community and the world."
When Junior died, Bill tweeted he had played with the NFL legend in a charity golf tournament just the day before.
Sad day....Played in a Charity Golf tournament yesterday with Junior and now he's gone. RIP my friend. Please say a prayer for him.— Bill Goldberg (@Goldberg) May 2, 2012
Junior's private memorial service is currently underway -- with only close family and friends in attendance.
Junior's scheduled to be buried at 1pm. As TMZ first reported, Junior was found dead in his California home on May 2nd after shooting himself in the chest.
