NFL legend Joe Montana was Saturday’s Most Valuable Grandpa after he helped take a grandchild away from an intruder.

The same spirit that drove the all-star quarterback to lead the San Francisco 49ers to four Super Bowl championships kicked in Saturday when Montana was confronted by an intruder in his home.

Montana, 64, now lives in Malibu, California, with his wife, Jennifer.

On Saturday, at about 5 p.m., an intruder entered their house, according to TMZ, which cited “law enforcement sources” as the source of its information.

Police believe the 39-year-old woman entered through an unlocked door.

Once inside, she saw a baby being held by a woman. The still-sketchy information did not say who holding the baby.

It is not clear how, but the intruder was able to gain hold of the infant and take the child to another part of the house.

There, Montana and his wife confronted the woman.

As TMZ reported it, the couple then had to literally wrestle the baby out of the woman’s arms.

After that, the intruder left.

Chance then worked against the intruder, TMZ reported.

Los Angeles County sheriff’s deputies were nearby on an unrelated matter, and were approached by someone in the Montana household who informed them of what had taken place, TMZ reported.
