The Oxford v Cambridge Boat Race is expected to go ahead
The University Boat Race is expected to go ahead after a suspected World War Two shell was discovered by the River Thames, police have said.
But some viewing areas may have to be suspended by the event organisers if it is deemed to pose a hazard.
The find was made near Putney Bridge, west London, on Saturday - a day before the 163rd Oxford v Cambridge race.
Work to assess what is believed to be "submerged ordnance" is continuing on Sunday morning.
A bomb disposal unit had to wait for the tide to go out to take a better look at it, police added.
The Thames river tide receded at about 01:00 BST and organisers will meet police later to decide if the race will be affected.
Crowds of up to 300,000 people are expected to line the banks of the River Thames.
Spectators have been warned to be vigilant following the attack at Westminster, reported the Telegraph.
"The security threat level remains at severe and, as always, we would encourage those attending to be aware of their surroundings and be vigilant," the Met said in a statement.

Roads in the area of the suspected bomb currently remain open.
The Met confirmed officers were in attendance on the northern bank of the river at Chelsea.
A statement said: "Police were called by a member of the public at approximately 13:50 BST on Saturday... reporting what they thought to be World War Two ordnance on the Chelsea shoreline by Putney Bridge.

Putney Bridge in west London links Putney in the London Borough of Wandsworth on the south side of the river with Fulham in the London Borough of Hammersmith and Fulham to the north
"Officers including the Marine Policing Unit are in attendance."
Michelle Dite, race director of the Boat Race, said on Saturday: "At this stage the races will go ahead as planned.
"Any decisions regarding changes to the event will be made in conjunction with the police."
The BBC understands the bomb was found by a passing sailor and was located on the Chelsea bank of the river on the north side of Putney Bridge.
The races start on the other side of Putney Bridge, with the women's race at 16:35 BST and the men's race at 17:35 BST.
